The Aish Rabbi Replies:

From the four specific references to Lillith in the Talmud, we learn that she is a wild-haired and winged creature with nymphomaniac tendencies (Eruvin 100b, Nidah 24b, Shabbat 151b). She is the mother of demons (Bava Batra 73a) and is said to "kill 100 of her demon children daily."

According to Rabbi Chiya, she "returned to dust" (Genesis Raba 22:7), and God proceeded to create a second Eve for Adam (Genesis Raba 18.4).
